群控系统服务端开发模式-应用开发-前端图片格式功能开发

一、添加视图

        在根目录下src文件夹下views文件夹下param文件夹下grade文件夹下，新建index.vue，代码如下

<template>
    <div class="app-container">
        <div class="filter-container" style="float:left;">
            <el-form :inline="true" :model="searchParams" class="demo-form-inline">

                </el-form-item>
                <el-form-item>

                    statusInfo({ id: ids, status:status }).then(res => {
                        this.getList()//更新列表
                        succ(res.message)// 提示结果
                    })
                }).catch(err => {
                    err(err.message)
                    return false
                })
            },
            // 每页条数切换
            handleSizeChange(val) {
                this.currentSize = val
                this.getList()
            },
            // 页数切换
            handleCurrentChange(val) {
                this.currentPage = val
                this.getList()
            }
        }
    }
</script>
<style lang="scss" scoped>
    .app-container {
        padding:10px;
        .roles-table {
            margin-top: 30px;
        }
        .permission-tree {
            margin-bottom: 30px;
        }
    }
    .el-image-viewer__close{
        color: #fff;
    }
    .roleId .el-select{
        width:100%;
    }
</style>

二、添加ajax请求

        在根目录下src文件夹下api文件夹下param文件夹下image.js，代码如下

import request from '@/utils/request'
// 列表
export function getList(params) {
    return request({
        url: '/param/image/get_list',
        method: 'get',
        params:params
    })
}
// 所有
export function getAll() {
    return request({
        url: '/param/image/get_all',
        method: 'post'
    })
}
// 获取
export function getInfo(data) {
    return request({
        url: '/param/image/get_info',
        method: 'post',
        data
    })
}
// 保存
export function saveInfo(data) {
    return request({
        url: '/param/image/save_info',
        method: 'post',
        data
    })
}
// 删除
export function deleteInfo(data) {
    return request({
        url: '/param/image/delete_info',
        method: 'post',
        data
    })
}
// 启禁用
export function statusInfo(data) {
    return request({
        url: '/param/image/status_info',
        method: 'post',
        data
    })
}
